I've owned a 500, a 1200 and a 4000. I've craved for a CD32 (later, when I grew up).
I've also used an a1000, an a2000. Never seen an a3000 though.
When I parted with my 500 (with 120MB scsi disk, and 3MB ram) for a stock a1200 with 80MB disk. I felt cheated by Commodore.
I loved my A4000PPC when I upgraded to that back when P5 released it.
But now my heart belongs to the A1200. Which it never really had in the first place. That was then reserved for the A500 and A4000.
Now I love it because of the simplicity, compatability and AGA.
I "can't" use my A500, and the A4000 is too bulky to have near by the TV for those Sensible Soccer, Pinball Fantasies and Lemmings bouts...
Now if I only could be done with the 1200 hacks I've got planned (mini psu and cdrom)
